Problem: PACCAR is recalling certain model year 2007-2014 Kenworth T800 and W900 trucks manufactured March 22, 2006, through July 15, 2013 and equipped with Primaax tridem rear suspensions and a pusher and/or tag axle. The affected trucks have brake chambers that take longer to apply or release the brakes than the required time limit. Thus, these vehicles fail to conform to the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 121, "Air Brake Systems."
Risk: Brakes that take longer to apply may lengthen the distance needed to stop the truck, increasing the risk of a crash.
Fix: PACCAR will notify owners, and dealers will modify the air brake system, free of charge. The recall began on January 15, 2014. Owners may contact PACCAR at 1-425-468-7400. Kenworth's recall number is 13KWL.
Recall 11V-127: Fuel System, Other
Problem: Paccar is recalling certain model year 2008-2012 kenworth t2000, t660, t700, t800, and w900, as well as model year 2009-2012 peterbilt 365, 367, 384, 386, 387, 388, 389, and 587 trucks equipped with paccar mx engines. The oil module centrifugal spinner filter cap in the paccar mx engine may become loose, possibly allowing the cap to come off and engine oil to partially discharge from the oil module onto exhaust components.
Risk: The discharge of engine oil onto exhaust components which are hot, such as when the engine is under significant load, may cause a fire.
Fix: Dealers will re-torque the oil module filter cap and install a secondary retention device on the secondary centrifugal spinner filter cap. This service will be performed free of charge. The safety recall is expected to begin during march 2011. Owners may contact kenworth at 1-425-828-5440 and peterbilt at 1-940-591-4196.
Recall 10V-535: Service Brakes, Air
Problem: Paccar is recalling certain model year kenworth t660, t700, t800 and w900 vehicles manufactured from december 22, 2008, through august 2, 2010, and equipped with ag400l air disc brakes. The air disc brake caliper could be installed on the wrong side of the drive axle potentially causing interference with the suspension bracket and the rear suspension as the outermost brake pads wear and the floating caliper moves inboard.
Risk: As this interference gets larger, this could eventually lead to reduced braking performance, increasing the risk of a crash.
Fix: Dealers will verify the correct orientation of the brake caliper and perform the necessary repair free of charge. The safety recall began on november 24, 2010. Owners may contact kenworth at 425-828-5440.
Recall 10V-308: Steering
Problem: Paccar is recalling certain model year 2008-2010 trucks equipped with trw steering shafts. The circumferential weld around the steering shaft tube that welds the splined tube to the non-splined tube may be mislocated. Mislocation of the circumferential weld may allow the splined tube and non-splined tube to rotate relative to one another during a low speed, high torque turn, possibly resulting in a separation of the two tubes.
Risk: A separation of the splined and non-splined tubes would cause a loss of steering control and increase the risk of a vehicle crash.
Fix: Dealers will inspect the steering shaft using a weld placement gauge provided by trw. Any steering shaft found to have been welded improperly will be replaced free of charge. The safety recall began on july 30, 2010. Owners may contact kenworth at 425-828-5440 and peterbilt at 940-591-4196.
Recall 09V-415: Power Train
Problem: Kenworth is recalling model year 2009 through 2010 t2000, t800, t660 and w900 trucks manufactured between november 12, 2008 and september 30, 2009. The axle u-bolts attaching the axle to the suspension leaf spring on certain ag400l rear suspensions may have received insufficient fastener torque during the installation process. The insufficient torque may allow the axle u-bolt to become loose, which may cause vibration in the rear suspension.
Risk: If multiple fasteners were to become loose, the rear axle may shift relative to the rear suspension leaf spring, which can result in loss of control and a crash.
Fix: Dealers will inspect the axle u-bolts for visible defects, including bent and/or smashed threads and re-torque the axle u-bolts to factory specifications. The recall began on november 4, 2009. Owners may contact kenworth at 425-828-5440.
Recall 09V-348: Engine and Engine Cooling
Problem: Paccar is recalling model year 2008-2010 kenworth t300, t270, and t370, model year 2009-2010 t800 and peterbilt model year 2008-2010 335, 340, and 367 vehicles built on cummins' diesel engine. The vehicles may be designed with a hard wired, dash-mounted switch that enables the vehicle operator to inhibit aftertreatment diesel particulate filter regeneration in environments where the operator believes it may be unsafe for elevated exhaust temperatures. Due to an issue with the logic in the ECM software in these engines, the switch may not function correctly, leading the operator to believe that the switch is in "inhibit" mode when it is not.
Risk: This condition will permit hot exhaust gases to exit the vehicle tailpipe, increasing the risk of melting or burning of nearby surfaces, or a fire.
Fix: Paccar is working with cummins to repair the engines free of charge please see 09e-046. The safety recall began on october 1, 2009. Owners may contact cummins at 1-800-diesels (1-800-343-7357).
Recall 09V-258: Steering
Problem: Paccar is recalling 2,096 my 2009 kenworth and peterbilt vehicles equipped with trw steering shafts. Mislocation of a circumferential weld may allow the splined tube and non-splined tube to rotate relative to one another during a low speed, high torque turn, possibly resulting in a separation of the two tubes.
Risk: A separation of the splined and non-splined tubes could cause a loss of steering control and increase the risk of a crash.
Fix: Dealers will inspect the steering shaft using a weld placement gauge and miswelded steering shaft will be replaced free of charge. The recall began july 31, 2009. Owners may contact kenworth at 1-425-828-5440 and peterbilt at 1-940-591-4196.
Recall 09V-239: Service Brakes, Air
Problem: Kenworth is recalling 3,423 my 2004-2009 t2000, t800,t600, w900 and t660 vehicles. Increased brake excitation in a certain vehicle configuration which includes bendix drum brakes, wide base low profile single tires, and an ag400 or ag460 rear suspension, due to its unique brake clocking and cam tube length, can cause fatigue and cracking to brake assembly components.
Risk: Cracking can cause a complete fracture of the cam tube, which could increase stopping distance and decrease parking brake hold capability.
Fix: Dealers will inspect the rear axle brakes assembly, replace cracked rear axle brakes assembly components where required, and install cam tube support brackets on all rear axle wheel ends free of charge. The recall is expected to begin or before july 25, 2009. Owner may contact kenworth at 1-425-828-5440.
Recall 09V-229: Power Train
Problem: Kenworth is recalling 9 my 2009 t800s vehicles equipped with dana front axle. The brake spider mounting fasteners attaching the brake spider to the front steer axle flange may have received insufficient torque during the installation process. The insufficient torque may allow the brake spider fasteners and brake spider to become loose.
Risk: This can allow the fasteners to shear and fall either onto the roadway or into the drum brake assembly, potentially allowing the brake to bind and causing increased stopping distance and a crash could occur.
Fix: Dealers will inspect and replace the brake spider mounting fasteners and torque them properly, as well as review the brake spider and steer axle flange holes for signs of vibration and fatigue and replace if necessary. This service will be performed free of charge. The manufacturer has not yet provided an owner notification schedule. Owner may contact kenworth at 1-425-828-5440.
Recall 09V-166: Service Brakes, Air
Problem: Paccar is recalling 140 my 2005, 2007-2009 t800, w900, and t660 trucks. The caliper mounting fasteners attaching the air disc brake caliper assembly to the torque plate may have received insufficient torque during the installation process. The insufficient torque may allow the air disc brake caliper assembly to become loose and possibly separate from the vehicle.
Risk: This could result in reduced braking capacity and also a road debris hazard, increasing the risk of a crash.
Fix: Dealers will inspect air disc brake caliper assemblies and replace the caliper mounting fasteners and torque properly. This service will be performed free of charge. The manufacturer has not yet provided an owner notification schedule. Owners may contact kenworth at 1-425-828-5440.
Recall 08V-485: Suspension
Problem: Paccar is recalling 130 my 2004-2009 t2000, t800, t600, w900 and t660 kenworth trucks built with an ag400 rear suspension, long stroke brake chambers, and wide base tires (Super singles). These vehicles may develop an increase in lateral and vertical axle movement. This movement may cause part or parts of the brake assembly (Brake cam tube support, brake chamber bracket, brake chamber, brake spider) to develop fatigue cracks, possibly resulting in the failure of the part or parts within the brake assembly.
Risk: A failure may reduce vehicle brake performance, increasing the risk of a crash.
Fix: Dealers will install the cam tube support brackets on all of the rear axle wheel ends. Inspect the rear axle brake assembly and replace it if cracked. The recall is expected to begin during november 2008. Owners may contact kenworth at 1-425-828-5440.
